Sheet conveying apparatus |
摘要 |
A sheet conveying apparatus which can correct a conveying velocity of a sheet is constructed by, a conveying unit to convey the sheet, a reader such as a CCD linear sensor for reading a fringe pattern formed on a pattern sheet while the pattern sheet is conveyed by the conveying unit, a detector to detect a conveying velocity of the pattern sheet on the basis of the pattern read by the reader, and a controller to control a conveying velocity of the conveying unit on the basis of the conveying velocity detected by the detector.
